andym85 Posted October 12, 2007 Report Share Posted October 12, 2007 i used to run two different batteries for quite some time in the past....never had any issues, people always say to keep them the same but i really dont think its gonna be that huge of a deal if u dont.. things to look out for: - well, make sure u fuse the positive run withing 18" of the battery at both batteries -if u ground ur batteries to the frame (or somewhere else) instead of wiring the grounds together, make sure u clean off the surface and scrape any paint off -try not to kill urself...lol Quote i likes me some audio stuff...

Thank you very much guys! Sunday im going to rewire everything, put the 2 batts in, Build a MDF box for it becuase its gonig behind my driver seat, buying terminals, 4gauge wire, fuse holders, fuses, Ahh one more question, What fuse rattings should i put on the batts? I currently have 1600 rms, but thats changing on tuesday as i'll be getting my 2 orion D5000's but i'll be running about 4K then... Thanks ever so much for all the replys! really appricate the help! i'll take pics aswell on sunday post them here.... Quote Link to comment Share on other sites More sharing options...
andym85 Posted October 13, 2007 Report Share Posted October 13, 2007 Maximum Fuse Size 00 awg 400 amps 0 awg 325 amps 1 awg 250 amps 2 awg 200 amps 4 awg 125 amps 6 awg 80 amps 8 awg 50 amps 10 awg 30 amps 12 awg 20 amps 14 awg 15 amps 16 awg 7.5 amps These are the recommended maximum fuse ratings for the corresponding wire size. Using a smaller fuse than what's recommended here will be perfectly safe. Quote i likes me some audio stuff... Link to comment Share on other sites More sharing options...
iceman88 Posted October 13, 2007 Author Report Share Posted October 13, 2007 dham its 4.30am here! lol so i guess i'd be fine if i put a 200amp ANL fuse for the moment, and once i put the D5000's in i'll put 2x 200amp ANL on each 4 gauge, Thanks alot for the info mate! cheers Quote Link to comment Share on other sites More sharing options...
kingsuv Posted October 13, 2007 Report Share Posted October 13, 2007 not really all weak. it's just that the strongest and highest amperage batts won't ever get fully charged and the smaller amp batts get overcharged to a degree due to their lower current resistance The easiest way to think about it is, if you pull a huge amount of amps from your power supply, your weakest battery will drain first. After that, your charging system and other batteries will work harder to compensate for the drained / weak battery. Quote Designing, building, and shipping boxes.

I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. Link to comment Share on other sites More sharing options...

Would that kill the ALT by any chance?? lol and in my above post i ment i'll put 1 fuse per 4gauge lol. Quote Link to comment Share on other sites More sharing options...
